Chastity and orgasm denial discussion

It’s been quite some time since I last wore any kind of chastity device, other than a leather belt that I occasionally put on. However, I’ve just purchased a Cb6000s to get back into the rhythm. I was wondering if those who wear CB devices could remind me about the best ways to start getting accustomed to wearing one again. Details such as which lubricant works well and how to break myself in properly. Thanks x
